Spark plug heat rating?

Spark plug heat rating?
My car runs a 40 thou skimmed head and about 20 degrees advance i think. It was mapped a while back and I've removed the plugs recently and they are white. A friend suggested that this means they are getting too hot and that I should change to a higher heat related plug?
I see mx5 parts do BKR6E-11 (which it already has in it) and the BKR7E-11.
I take it I want the 7E's?

It's on megasquirt and has recently been mapped.
I have no idea about that sort of stuff I drop it off to be mapped then pick it up done.
On the dyno printout it's AFRs looked ok but it does run a lot of timing advance so maybe that's it. It's back down for a map check next month I'll met
Nation it maybe being lean then
